Using SO2 standard gas with a concentration of 9 999.7 mg·m-3, high-purity N2, and 99.5% O2, the SO2 concentration is 2 500 mg·m-3, and the oxygen content is 0%, 5%, 10%, 15 % Of simulated flue gas.
The SO2 standard gas, high purity N2 and 99.5 percent O2 with concentrations of 9 999.7 mg.m-3 were used, and the so2 concentration was rationed to 2,500 mg m-3, with oxygen content of 0%, 5%, 10% and 15% analog flue gas, respectively.
The simulated flue gas with SO2 concentration of 2 500 mg · M-3 and oxygen content of 0%, 5%, 10% and 15% were prepared with SO2 standard gas of 9999.7 mg · M-3, high purity N2 and 99.5% O2.<br>
